Load SSH Keys Produced by ssh-keygen

See more SSH Key Examples

Demonstrates how to load the public and private keys produced by ssh-keygen. C++

#include <CkSshKey.h>

void ChilkatSample(void)
    {
    bool success = false;

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // We first generate a key like this:

    //     ssh-keygen -f stg.chilkat.id
    //     Generating public/private rsa key pair.
    //     Enter passphrase (empty for no passphrase):
    //     Enter same passphrase again:
    //     Your identification has been saved in stg.chilkat.id.
    //     Your public key has been saved in stg.chilkat.id.pub.
    //     The key fingerprint is:
    //     SHA256:hkbgexkspxYTa8rYUxouRU8Gi7lbbsT6dSLX+JlStKk me@example02240
    //     The key's randomart image is:
    //     +---[RSA 2048]----+
    //     |  o.=            |
    //     | + * =           |
    //     |o + X =          |
    //     | O * O.+         |
    //     |+ @ +.=oS        |
    //     | A o =+.         |
    //     |o + =oo          |
    //     | o +E+ o         |
    //     |  .  .+          |
    //     +----[SHA256]-----+

    // 

    // The public key (generated to the file stg.chilkat.id.pub) contains this:
    // ssh-rsa AAAAB3NzaC1yc2EAAAADAQABA.. FDt+dKJEkhw8I7LpEi17diB9 me@example02240

    // First let's load the public key:
    CkSshKey pubkey;

    success = pubkey.FromOpenSshPublicKey(pubkey.loadText("qa_data/sshKeys/ssh-keygen/stg.chilkat.id.pub"));
    if (success == false) {
        std::cout << pubkey.lastErrorText() << "\r\n";
        return;
    }

    std::cout << pubkey.lastErrorText() << "\r\n";
    std::cout << "Successfully loaded the public key." << "\r\n";

    // Now try the private key, which contains this:
